Dragonfly Mate Puzzle (Rated 1500): Mate in 1 — Dragonfly-Mate Pattern
This puzzle is a clean mating pattern built around a knight jump that lands on a protected outpost near the enemy king. The key idea is that the checking piece cannot be captured because the capture square is controlled, while the king’s escape squares are already covered by White’s active queen and bishop. That combination of direct check, restricted flight squares, and piece coordination is what makes the finish immediate and forcing.
